Microwave Measurement - Electrolux MC2660E (EU) Service Manual

COMPONENT REPLACEMENT AND ADJUSTMENT PROCEDURE
INNER SEALER FILM
Installation
1. Tear away the backing film.
3. Put the pasted side of the inner sealer film
on the door panel.
After adjustment of door latch switches, monitor
switch and door are completed individually or
collectively, the following leakage test must be
performed with a survey instrument and it must be
confirmed that the result meets the requirements
of the performance standard for microwave oven.
REQUIREMENT
The safety switch must prevent microwave
radiation emission in excess of 5mW/cm
point 5 cm or more from external surface of the
oven.
PREPARATION FOR TESTING:
Before beginning the actual test for leakage,
proceed as follows;
1. Make sure that the test instrument is operating
normally as specified in its instruction booklet.
Important:
Survey instruments that comply with the
requirement for instrumentations as prescribed
by the performance standard for microwave
ovens must be used for testing.

2. Place the oven tray into the oven cavity.
3. Place the load of 275 ± 15 ml of water initially at
20 ± 5°C in the centre of the oven tray. The water
container should be a low form of 600 ml beaker with
inside diameter of approx. 8.5 cm and made of an
electrically non-conductive material such as glass or
plastic.
The placing of this standard load in the oven is
important not only to protect the oven, but also to
insure that any leakage is measured accurately.
4. Close the door and turn the oven ON with the timer
set for several minutes. If the water begins
before the survey is completed, replace it with 275ml of
cool water.
5. Move the probe slowly (not faster that 2.5cm/sec.)
along the gap.
6. The microwave radiation emission should be
measured at any point of 5 cm or more from the
external surface of the oven.
